How to Preview Your Page’s OG Appearance on Social Media

Graham keywordnumbersJuly 6, 20266 min read

Ever wondered exactly how your web page will look when shared on Facebook, Twitter/X, LinkedIn, or other social platforms? This guide will show you how to preview and perfect your OG (Open Graph) and social meta tags, so you can ensure your site stands out in any feed.

What is an OG (Open Graph) Preview?

The OG preview is essentially a sneak peek at how your page will appear when someone shares its link on social media. Social platforms use meta tags—like Open Graph (OG) and Twitter Cards—to decide what image, title, and description to display.

Previewing your OG appearance helps you:

Spot issues (wrong or missing images, cut-off titles)

Optimise click-through rates with compelling headlines and visuals

Ensure brand consistency across platforms

Why OG Previews Matter

A polished OG preview can mean the difference between someone clicking your link—or scrolling straight past. Each platform interprets tags slightly differently, so a quick check is vital for:

Brand credibility: A professional, on-brand image and copy boost trust.

Higher engagement: Clear, enticing previews encourage more clicks and shares.

Controlling your message: Prevents platforms from pulling the wrong content or auto-generating awkward snippets.

How OG Previews Work

When a page is shared, platforms like Facebook and Twitter look for specific meta tags in your HTML:

og:title – The title of your page

og:description – A summary description

og:image – The preview image

og:url – The canonical URL

Twitter/X* also uses:

twitter:card – Type of card (summary, large image, etc.)

twitter:title, twitter:description, twitter:image

LinkedIn* primarily uses OG tags, with some platform-specific tweaks.

Previewing Your Page: Step-by-Step

You don’t need to guess how your content will look. Use a free OG Preview Tool on KeywordNumbers.com to see previews for Facebook, Twitter/X, LinkedIn, and more—all in one place.

Example: Testing an OG Preview

Let’s say you have a blog post about "10 Best Hiking Trails" at https://yoursite.com/hiking-trails.

Your OG tags might look like:

`html

Worked Example: Distances in Both Units

Suppose your post lists:

Trail Name	Distance (km)	Distance (mi)
South Downs Way	160	99.4
Ben Nevis Path	17	10.6

Including both metric (kilometres) and imperial (miles) units in your OG description ensures clarity for UK, US, and international audiences. When you run this page through the OG preview tool, you’ll see exactly how these details appear on each platform.

Platform Differences: What to Watch For

Platform	Image Size (pixels)	Description Length	Title Length
Facebook	1200 x 630 (recommended)	Up to ~110 characters	Up to ~60 chars
Twitter/X	1200 x 628 (large card)	Up to ~70 characters	Up to ~70 chars
LinkedIn	1200 x 627	Up to ~150 characters	Up to ~70 chars

Tip:* Always use high-resolution images (at least 1200px wide). Keep titles and descriptions punchy to avoid cut-off text, especially on mobile.

How to Fix Common OG Preview Issues

Wrong image showing: Check your og:image URL and ensure it’s absolute (includes https://).

Missing description or title: Make sure your meta tags are present and correctly formatted.

Updates not showing: Social platforms often cache previews. Use their debug tools to force re-crawling:

Facebook: Sharing Debugger

Twitter/X: Card Validator

LinkedIn: Post Inspector

Questions people are actually asking

How do I preview my website’s OG tags for Facebook, Twitter, and LinkedIn?

Use a free OG preview tool like the one on KeywordNumbers.com. Simply enter your page URL and view accurate previews for each social platform.

What image size should I use for OG previews?

Aim for at least 1200 x 630 pixels, which works well for Facebook, Twitter/X, and LinkedIn. Larger images scale down, but small images may appear blurry or be replaced.

Why is my OG image or description not showing correctly?

Double-check your OG meta tags for typos, use absolute image URLs, and clear the social platform’s cache using their debug tools.

Can I see how my page will look on Twitter/X specifically?

Yes—OG preview tools show Twitter/X cards, including summary and large image layouts. You can also use Twitter’s Card Validator for a live test.

Do I need separate meta tags for each platform?

OG tags cover Facebook, LinkedIn, and others. For Twitter/X, add optional twitter: tags for best results. If not present, Twitter/X may fall back to OG tags.

How can I update my OG preview after changing my tags?

After updating your meta tags, use the platform’s debug tool (like Facebook Sharing Debugger) to refresh their cache, then re-preview.

What happens if I don’t set OG tags on my page?

Social platforms will try to auto-generate previews, which often leads to poor or incomplete results—random images, cut-off text, or missing branding.

Previewing your OG appearance is a quick win for better social engagement and a more professional online presence. Try the OG Preview Tool now and make sure your next share looks its best!
